Last week I played with the knots to make a quick deviation, with no lanyards with no rings and no choked carabiners, and I made this. Looking at it, it seems very similar to MigroveSpecia knot, made by Joey Tree, which is a knot ending with a slip knot, that can be retrieved. Even if they're similar, mine works in a completely different way: it's not retrievable, I can choke it on a smooth pole (so it won't slide), on the carabiner I can also make a 3:1 MA, and the thing that I like most is that it's very quick to do.
